I backed up my transaction log file using this:
BACKUP LOG iTest2_AELetters TO DISK = N'nul'(yes I know this breaks the log chain - it's expected in this intance)
But after I run it my t log is exact same size. I have refreshed many times.
I am using SQL Always On on this DB.
We use AlwaysOn availability groups, which has 2 SQL nodes configured (version: 11.0.3373.0), my full and differential backups are working for all my databases, however I am unable to perform any LOG backups.
I have double checked my Availability Group settings, and the backup preferences is set to: 'Prefer Secondary'
I've tried creating a maintenance job as well as using Ola Hallengren's maintenancescript job to back them up, but nothing is written to the drive. All jobs return successful every time, and take less then 3 seconds to run. There are no events being written in the SQL error log or event log.
Hello All,The setting is SQL server 7, on Windows NT.If the distributor can not access the log on the publisher database ( butsubscribers are not deleted yet), will the full backup of the publisherdatabase truncate the transaction log? My guess is, it will not truncate thelog.Can any one confirm please?Thanks,Mokles
View 2 Replies View RelatedHi all,
I have set up a maintenance plan to backup my databases but when I view the maintenance plan history the transaction log backup steps have a success tick but a message saying :
"Backup can not be performed on this database. This sub task is ignored"
I have looked in my backup directory and only see *.BAK files and no *.TRN.
The transaction logs are supposed to back up at 1AM and the databases at 2AM
All my databases being backed up have the truncate log on checkpoint option set. Is this best practise according to my backup schedule ?
Help !!!!

Tim
Coming from a (mostly) Oracle shop, I am unclear how SS transaction logswork as far as up to point of failure recovery goes.I have the few MSSQL databases I look after in full recovery mode, and Iset up maintenance plans to back these up online on a daily basis. Inthe research I did it was recommended backing up the transaction logs aswell on a frequent basis to ensure recovery to POF or point in time.I had assumed that they work like Oracles archive logs, in that oncethey are full they are archived to disk in case they are needed, toduplex destinations if need be. Does SS do this, or do I need to bebacking up transaction logs on an hourly (or shorter) basis? In lookingat enterprise manager I see that it does not look like the transactionlogs are archived anywhere, but overwritten once filled up, similar toOracle noarchivelog mode, in that if you lose your online redo logs oranyone of them has recycled since your last backup, then you can onlyrecover to the last good backup.Is this a correct assumption? Should I be backing up transaction logshourly to make sure I can have PIT or POF recovery?thanksTG

Hello,
how can i view the content of a archived (backed up) transaction log?
DBCC LOG only works with online logs.
Thx for your answer

Has anybody encountered a physical size limit for a sql server 2000 transaction log running on win2k?
Transaction log reached ~6Gb before rolling back the delete stating transaction log was full. There was 42Gb free on the server and the log was set to unlimited growth.
Hi ,I have a file presumably backup of a User database from a SQLServer(2k) database. I want to load/restore that in a local SQL Serverto be able to see the table , views , etc present in the database.How do I do that ?Thanks,Arijit

View 6 Replies View RelatedI'm taking the liberty to announce the availability of a suite of articles on my web site about error and transaction handling in SQL Server. In total there are three main parts and three appendixes.
The first part is a short jumpstart, while Part Two is a long in-depth discussion of what can happen in SQL Server in case of an error and what commands that are available. Part Three covers implementation and has lot of examples as well as a facility for logging and raising errors.
The appendixes cover special areas: linked servers, the CLR and Service Broker.

I have a Database that is set to Simple Recovery mode.
It is not clearing the log and the transaction log is growing.
I thought that it would clear the log upon checkpoint?
How can I force the Transaction Log to clear since NO-TRUNCATE is no longer available?
I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.
I'm trying to create a cte to return a list of lots and every period between the first and last transaction date for each lot. I've gotten this far:
SELECTIntLotKey
,DATEPART(YYYY, StartDate)StartYear
,DATEPART(MM, StartDate)StartPeriod
,DATEPART(YYYY, EndDate)EndYear
,DATEPART(MM, EndDate)EndPeriod
[Code] ....
This gives me the following results:
IntLotKeyStartYearStartPeriodEndYearEndPeriod
271532013120135
28468201312201312
2846920131201312

28472201312201312
593022013120131
593032013120131
Now what I need is something that looks like this:
LotKeyYearPeriod
2715320131
2715320132
2715320133
2715320134

Some lots may not have any transactions for some of the periods between the start and end dates but I need to report every period between the start and end period for each lot. I have a period table that I thought I could use but haven't come up with a way to get the results I'm after.

I understand why they do not work but I'm struggling to figure out how to update the 'PeriodPrevPaidInFull' field.

Any way to have a process run that will not write its changes to the transaction log? I have a process that runs every three hours and has a huge impact on the transaction log (it becomes larger than the database itself). We do hourly backups of the transaction log and normally it is reasonably sized but when this process runs, it gets HUGE.
The process takes source data, massages it and writes it to summary tables. It is not something we need to track as we can recreate the summary tables if needed and it has no impact on the source tables.
Everything is driven through a stored procedure. Is there a way to run a stored procedure and tell it that nothing it does should be written to the transaction log?

I know Oracle provide pragma directives to execute autonomous transactions which i used before on Oracle for logging. Now i want to repeat the same in SQL Server but unfortunately i found such pragmas are not existing in SQL Server.After several google searching, i have found that i can use loopback linked server to generate autonomous transaction calls.
If i have Server A & Server B where server B is a loop back server of Server A and all my objects are existing on Server A. I just wanted to user Server B for logging only. should i have logging tables on Server B? Logging procedures on Server A? and call logging procedures (via Execute ) from application procedures residing on Server A?
Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs. I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool. The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initial replica set up times.
I have a setup of transaction replication between one publisher and subscriber in the Same server.Now, I need to add a new subscriber to the existing publisher. So publisher database name is DB_A and Subscriber 1 name is DB_B. So the new subscriber will be DB_C. Is this kind of setup possible on one server?
If yes then at the time of reinitialization is it going to apply the snapshot on DB_B as well as DB_C?Also let say if due to disk error DB_B gets corrupted then will data be still replicated between DB_A and DB_C? (Assuming publisher, subscriber 1 and 2 are sitting on individual disks).
I have a stored procedure that does the following
BEGIN TRANSACTION OUTERTXN
BEGIN TRANSACTION
Copy records from live to archive
END TRANSACTION with commit or rollback
execute sproc to write audit log with success or fail
IF transaction was committed
BEGIN TRANSACTION
Delete records from live the archive
END TRANSACTION with commit or rollback
execute sproc to write audit log with success or fail
End IF
END TRANSACTION OUTERTXN with commit if both inner transactions were successful or rollback if either failed
If either inner transaction rolled back execute sproc to write audit log saying whole process is rolling back End IfMy problem is that if the outer transaction rolls back then I am losing the two audit records because they are part of the transaction scope. I want these executes to commit even if the master transaction fails.
Hello!
We have unusual situation. We increased the size of transaction log up to 100MB.
After we run the transaction log backup the physical size of transaction log file getting smaller and smaller from 100 to 88 and then to 76 and so on.
Do you now the reason?
Thank you,

I have a very serious problem, if somebody can help me quickly. my transaction log file is getting bigger and bigger even after truncating. today morning when i checked, it was 1.5 GB, by evening it has gone upto 3GB, the total size of the database is 3.4 GB, out of which 3GB is Transaction log. why is it growing heavily!!!!!!!!. there is not much transaction happening. even after truncating the transaction log it is still showing 3gb.
help!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I currently have an database that is 110 mb and grows on an average of 5mb a week. THe enviornment is IIS 5.0 /ASP /SQL 6.5. However I find myself continously increasing the log file since it frequently fills up. At this point it is 300mb and can be filled in less than an hour with an average of 35 users. I realize that this file has alot of overhead and is affected directly by the application making the updates. Last week on a busy day (time card app) I witnessed the log increase from below 75% to 100% in a minute, forcing me to truncate the log. This application is an administrative nightmare! Any ideas what could cause this type of activity in the trans log.
View 3 Replies View RelatedHi!
We have here a small database (around 400 MB) with simple recovery. Also autogrowth is active.
But why does the transactionlog also sized up, when it is not in use?
Our TL is around 100 MB and filled with 5 MB.
Everytime the DB gets bigger, the TL also....
This isin continuation with my previous query. If i cannot reduce th T Log size , how can i stop it from increasing further. Can i make secondary log files which can be deleted later on?

Hello dear friends,
In my database i am not able to take the backup of transaction log.
Even if i took the back up and then shrunk the file it doesnt make any change to my transaction log size.
Still the size is same.
So in every two weeks i am restarting my server.
Once it is restarted then it is ok for another 2 weeks.
After 2 weeks my transaction log size will be more than the size of my datafile.
Can you suggest your openion.
No replication or log shipping exist.
Thank you

Hello, everyone:
I am deisgning the transaction log file, and having the rough idea for transaction numbers per hour. How to determine each transaction size?
Thanks a lot.
